Yep, no issues with fitment.

All I would add is that please bear in mind that the engine can sit further back in a LHD mini(due to no steering rack fitting issues).

Therefore the exhaust will fit.

In a standard round nose RHD when Mattg tried it did not fit with salexander manifold. Be careful in not wasting your money.

I would also have thougth this would affect the radiator fitting as well, as moving the engine back will help with clearance in this area.

Good points Darren, I wouldn't have thought of that.

You can see how tight the exhaust header is sitting in the front. You can slide a piece of paper through right now, but that's about all.

K&N Air Filter on!

Maybe we should try an alternate radiator location?

Great points Darren thanks alot!!..

Unfortunatly I have a servo that occupies that area so Im not able to follow suit there!...

Must say it looks nice and snug though!

Any room to slide it in front of the bell housing right behind the grille?

Yeah thats where it has to go, but its a specialist part from MattG at 16vminishop. Its a twisted Ally rad but is very expensive 600

I live Travolis solution but cos we are right hand drive we have the cluch and brake masters there (and servo in my case)

It would have to sit on top of the slave cylinder, which only gives ~10 inches of height. MattG's twisted radiator would probably work, but I'm not "sold" on the look of it. The best solution right now looks like the following, if it'll be large enough to cool the motor:

Have you considered a "twin pass" radiator design. I have one of these on my Dax Rush and it works very well.



Water enters at the top goes down one side of the rad along the bottom and then back up to the top. I did this because space was limited and the inlet and outlet were both in the same general area. This design allowed for simple pipe runs.



Cheers Mike

Are you sure the radiator will be big enough to cool the engine?

Also the radiator is only going to suck in hot air, when at idle?

On the move you also arent going to get any air flow though the radiator

I would have thought you would at least want a small radiator front mounted and then a side one.

When we first ran my vtec we used a MPI mini rad up front with a small bike one mounted to the side. It was ok all the time you were moving but as soon as you stopped then the temp would go up and up, even the fan (mpi mini) would not bring it back down. We had to change the mpi mini one to a custom one to put up front and we have still kept the small bike one on the side. Seems ok now.

You will not have a lot of air passing through the rad if you fit it on the side and im not sure it will be up to the job. Be a shame to spend money having it custom made and then have to scrap it.

Good input, gents.

VTEC Steve, is yours a lengthened or standard length front?

You are right, it would be a shame if it doesn't cool as needed.

The radiator being built is supposed to have some sort of extra cooling ability.. more rows in the same space. Maybe that'll save me. They said they cannot guarantee it will cool enough, but did say that some hot-rodders are running 500hp V8's on the street with a smaller core size.

If absolutely needed, we can make a shroud that directs all the air from the front grille straight into the radiator also.

It's an adventure!

Working with the Mini Tec pedal assembly. It is hitting the firewall box and the pedals themselves are too close to the floor. There will be some customizing work needed.

Hi Travoli,

A radiators behaviour can be affected by the numbers of fins per inch "fpi" (which is I guess your comment about more rows) and the thickness of the core - amongst other things.

But they all rely on airflow through the radiator matrix, ironically when the numbers of rows or fins per inch is increased then the air flow through a rad is reduced as the increased fins or rows creates more of a 'blockage' per unit area.

There is no substitute for air flow, you can double the size of a radiator, but if no more air flows through it, it will not improve your cooling. Airflow, Airflow, Airflow

Fans can / will only help when the car is stationary - so try not to rely on them for general cooling.
